In Saints Row: The Third (aka Saints Row 3) for the PC, PS3, and Xbox 360, you can streak around town to gain some respect, and to goof off a little bit.
In order to streak, you need to go to your crib or to a clothing store and remove all clothing, including your underwear.
Once you are completely naked, go outside into a busy area and double tap Down on the d-pad if you’re on a console. If you’re on PC, press the X button twice.
As you’re streaking, you want to run into as many people as you can, as quickly as you can to keep it going and to keep getting more and more respect.
Once you’ve had all the fun you can have, just let the timer run out to finish.
